We explore electromagnetic wave properties and the electromagnetic spectrum. Unit 6 Segment F: Electromagnetic Wave Properties We explore electromagnetic wave properties and the electromagnetic ...

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...

In the last few weeks I've been working on a slightly more formal version of this post on black-body radiation for use in something else. One of the tricky things in writing about the development of ...

The terahertz range has been barely exploited compared to the rest of the electromagnetic spectrum. But as Sidney Perkowitz argues, our ability to detect radiation at these wavelengths has proved ...

We all think that the visible spectrum of light — every color we can see — is represented in the rainbow. But this isn't actually true. When you hold up a crystal prism to a beam of light, you see red ...
